Have a very fussy ds who is 6 months old. he takes solids three times a day(which is no problem!)he took a dream feed of ebm untill at 4 1/2 momths he woke up and refused a bottle. He has since refused a bottle on ALL occasions. he does take ebm from a cup but only an onz or two. I am back at work and desperatly need him to take more milk. Finally he accepted a bottle of ebm twice today and I am reluctant to put him back on the breast. Is it possible to purely pump without drying up my milk suplly, Please help???
